In vbox_crtc_set_base_and_mode() we update all the crtcs when the single_framebuffer setting changes, including the one on which vbox_crtc_set_base_and_mode() was called, so we end up doing vbox_do_modeset() on it twice. This commit skips the crtc on which we are updating in the loop to update the other crtcs. This commit also removes the vbox_set_view() call from the loop, vbox_set_view() does not depend on the single_framebuffer setting and it was being called on the passed in crtc parameter and not on the crtci local iterator value (typo), so it was a no-op already.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
